    Abstract: Apparatus for contacting a liquid reaction solution with a gas in separate reaction chambers within a single reaction vessel wherein the liquid reaction solution is continuously circulated between a first reaction chamber and a second reaction chamber within the reaction vessel but providing at least two side-by-side reaction chambers in open flow communication at their upper and lower ends with a gas supply means associated with each said chamber for introducing a gas in a finely divided form into the lower ends of each said chamber, and said gas supply means including flow control means whereby the rate of upward flow of gas in one of the chambers is greater than the rate of upward flow of gas in the other chamber so as to lower the density of the liquid reaction solution in the one chamber and provide continuous upward flow of liquid reaction solution and gas in the one chamber and downward flow of liquid reaction solution countercurrent to the flow of gas in the other chamber. The process and apparatus are particularly adapted for continuously carrying out two distinct chemical reactions between a liquid reaction solution and two different gases in a single reaction vessel, such as a catalytic oxidation-reduction process for removing hydrogen sulfide gas from a process gas stream.

    Abstract: Spheroidal polymer beads having a uniform size are prepared by polymerizing uniformly sized monomer droplets formed by the vibratory excitation of a laminar jet of monomeric material flowing in a continuous liquid medium containing a suitable suspending agent. For example, a laminar jet of a monomer mixture comprising a monovinylidene aromatic such as styrene, a polyvinylidene aromatic such as divinylbenzene and a polymerization initiator can be subjected to vibratory excitation and the resulting monomer droplets polymerized to yield copolymer beads having a narrow particle size range distribution. The resulting copolymer beads can be employed to prepare high yields of ion exchange resins exhibiting superior properties, particularly in continuous ion exchange operations.

    Abstract: Apparatus for conducting a continuous, pressurized liquid-state reaction while maintaining internal recycle. The apparatus has a perforated barrier plate which separates a reaction zone from a reboiler zone and has a by-pass conduit which connects these two zones. Control devices maintain the liquid levels in the reaction and reboiler zones. A heater in the reboiler zone evolves vapors in that zone, which vapors return to the reaction zone through the perforated barrier plate.
